Daniel Arsham’s latest exhibition, “The Future Was Then,” demolishes our expectations of an art gallery by recreating the space to feature 300 feet of white walls with excavated centers. The walls communicate with each other, visually creating the outline of a human. Visitors immediately become part of the piece as they walk through the walls, which separate a series of white rooms. Each of these rooms hosts a centerpiece of artwork ranging from hooded figures to a torso-less body. The exhibition moves seamlessly between creation and destruction, introspection and awareness.
